I have an early 90's Sea Ray ski boat and the fuel vent is in the back corner on the port side. We started wakesurfing and with the weight, the vent ends up being under water the entire time. Took a few weekends to figure out that water was getting into the gas tank and then my engine.

My question is, can I replace the vent with one that wont allow water in, or would it be better to re-reoute the vent to the starboard side? Has anyone done this before?

Yea I would suggest getting rid of the I/O and get your crew safe and away from that prop. Hopefully you keep your crew tight and everyone understands the possible consequences of riding behind your boat. I would hate to hear about someone being chopped up and causing a huge lawsuit and the possible threat of banning surfing as we already have problems with that

Do you mean a direct drive Ski Ray? If not, you should definetly not be surfing behind a I/O. Like Dax said, you can move the vent to the other side. You can also install a fuel/water separator that will help with water coming in.

It might work to route it to starboard, but only till you get a goofy footer in your crew. I think it would be easier and cover you no matter what if you just moved it forward. Most of the newer boats the vent is forward of the windshield just under the rub rail. I think it would be easier to go forward than have to cross the boat anyway.

Alex, I don't personally know of any but I guarantee people are surfing I'O's. Probably someone on this site right now. I doubt anyone is going to admit it because they will get flamed. NO WAY your getting me behind one!!

What's worse, is one weekend I was on Douglas Lake in TN and we were wake surfing, and an outboard powered boat with a bunch of highly intoxicated individuals decided they wanted to try... They grabbed a waterbed mattress and filled it or ballast, and were trying to surf behind the outboard on a kneeboard and I really thought they were going to kill themselves.

As for Alex's question, I have fallen. Few times behind my Centurion when I get too close and have grabbed the swim platform on some of those cases, so I am sure I could have put my body in contact with an I/O propeller.

Thats scary. No way I'm doing it with the revolving prop of death under the nose of my board. I prefer the prop of the boat well under the boat. I said it in another thread. Someone surfing an I/O is going to get killed or maimed and the sport will be banned.
